SPECIFICATION forming part of Letters Patent No. 239,700, dated April 5, 1881.

Application led December 10,1880. (No model.)

To all whom it may concern:

` Be it known that I, SOLOMON I. BAUGH- MAN, ot' Herring, in the county ol' Allen and State of Ohio, have invented a new and Improved Plow-Ulevis, of which the following is a specification.

The object of this invention is to provide a simple device for regulating the depth of the furrow made by the plow.

Figure l is a side elevation of a section' of a plow-beam with the device in position thereon. Fig. 2 is a plan of thell same, and Fig. 3 is a side elevation -of a modilication of the device.

Similar letters ot' reference indicate corre- -spondin g parts.

In the drawings, A represents a plow-beam.

B is a metal strap passing over the end and upper and lower faces ot' the beam A, to strengthen the same.

C is the clevis. swiveled on the pin a, that passes laterally through the plow-beam A, and said clevis C has an ear, b, projecting upward from each side thereof', above .the upper face ot' the beam A, and between these ears b b is swiveled a plate, D, having a central screwthread, as indicated at d, through which plate D the adjusting screwrod G is passed.

In the rear of the clevis C a bolt, E, having ascrew-threadedhole,f, made through its head, is passed'down through the strap B and beam A, and secured in position by thepnut g ou its end, the head L of said bolt E projecting above the upper face ofthe beam A,and having passed Ahorizontally through it the rod H, that is designed to extend tothe plow-handle, within easy reach of the operator. E an eyebolt, F, for supporting the rear prolongation of the rod H, is'passed down through beam A and secured in place by a uut, 7c.

A short rod, G, provided with a left-hand' screw-thread `and with an eye, m, is passed plane.

In rear of the bolt from the rear through the hole d of the swiveled plate D, and a longer rod, H, provided with a right-hand screw-thread and with a hook. n, is passed through the hole f of the bolt E, and connected by means of its hook n with the eye m of the rod Gr. .l This rod H is prolonged rearward through the eye of the eye- Figs.1 and 2,is hinged orjointed on both sides,

as shown at p, to the lugs N, that are firmly bolted on either side of the plow-bea1u A, so that said clevis O is free to move in a vertical Said clevis C is in all-other respects the same as that shown in Figs. l and 2.

I am aware that itis not new to raise or lower a draft-link plate by means of an angled lever on the beam connecting by a link with a handlever; also, that it is not new to coinbine a wheel, worm-shaft, rack, and pinion to raise or lower a clevis 5 but What I claim is- The combination, with a clevis, O, pivoted at a and having the ears b b, of the plate D, swiveled in said ears and centrally threaded, the looselyjointed and reverselythreaded bolts G E, the fixed nut jf, the guide F, and the crank 0, rigidly connected with bolt E, as shown and described.
